Coach Anthony Lynn said Friday that Bosa’s first foot injury had healed but
that he suffered a new injury during Wednesday’s practice. Bosa first injured
the foot on Aug. 7 during training camp and missed the preseason.

The Chargers had been cautious with Bosa during the preseason, hoping that
another injury wouldn’t occur.

“He’s real frustrated. He’s been waiting for a while to get back on the
field,” Lynn said. “It’s going to be week to week. We hope it doesn’t linger but
it could.”

This will be the first time Bosa has missed a game because of injury since
being selected with the third overall pick in the 2016 draft. He has 23 career
sacks in two seasons, including an NFL-record 19 in his first 20 games.

Bosa led the team last season in tackles (54) and sacks (12.5) while being
second in tackles for loss (17.5) and quarterback hits (22).

With Bosa’s injury, the Chargers will be without two starters on their
defensive line. Defensive tackle Corey Liuget is serving a four-game suspension
for violating the NFL’s policy on performance-enhancing drugs.

Isaac Rochell will get his first NFL start in Bosa’s place. The second-year
player saw extensive playing time during the preseason and led the team in
tackles for loss (3) along with two sacks.

“Isaac had a great camp. He’s grown like a weed, stepped up and got the job
done,” Lynn said.

Rochell said the increased snaps have allowed him to develop more confidence
and also gain the trust of coaches. He added that “you don’t want your coaches
to feel like they are in survival mode.”

The defense’s biggest challenge this week will be containing Patrick Mahomes.
The second-year quarterback uses his athleticism to keep plays alive, which has
led to big gains downfield.

“He has a strong arm but has the threat of running,” Rochelle said. “With the
other threats they have, there are going to be a lot of challenges.”

Lynn also said that he expects tight end Antonio Gates to be active for
Sunday’s game. Gates re-signed with the team Monday Youth
Mike McGlinchey Jersey , and Lynn said it looked as though Gates
picked up where he left off last season.

Michael Griffin says his 10-year NFL
career was a blessing that lasted far longer than some of his former teammates
at the University of Texas.

The two-time Pro Bowl safety officially ended that career Monday by signing a
one-day contract with the Tennessee Titans and retiring with the franchise that
drafted him with the 19th pick overall in 2007. Griffin, who wore No. 33 in his
career, retired at the age of 33.

"I can't say enough, thank y'all, just thank y'all," Griffin said at a news
conference inside the team's indoor practice field. "That's probably all I can
say is just thank y'all because it's a blessing, and I'm so thankful to have
that opportunity for the last nine years to play for this organization."

Griffin started 10 games as a rookie and played 141 games over nine seasons
with Tennessee, including 103 straight between 2007 and 2013. He remains the
franchise's all-time leader in tackles by a safety with 912. Griffin also had 25
interceptions, seven sacks, 11 forced fumbles and six fumble recovers with his
best season in 2008 with seven interceptions.

Controlling owner Amy Adams Strunk thanked Griffin for his nine seasons with
the Titans and wished him the best in retirement.

"He was such a dependable player for us during his time here Adidas
Gabriel Landeskog Jersey , missing only three games over nine
seasons, and he was always among our leading tacklers," Strunk said in a
statement. "His play earned him two Pro Bowl selections and the respect of his
teammates. Michael also was invested in our community, finding ways to make a
difference."

The Titans released Griffin in February 2016 when he was tied with Corey
Graham of Buffalo for the most games played by a safety in the NFL between 2007
and 2015. Griffin signed with Minnesota but didn't play a game. He then signed
with Carolina and started six of 13 games with the Panthers in 2016. He finished
his career starting 134 of 154 games played in 10 seasons.

Griffin spent the 2017 season working out in case a team called and finished
his degree at Texas. He said even when he was with the Vikings and Panthers he
always felt he remained a Tennessee Titan.

"I was always cheering my guys on, always texting them if someone went down,
ask how they were doing, keep their heads up, if someone was released whatever
it may be," Griffin said. "I always stayed in contact with those guys."
